Overview
R5F12048MSP#50 from Renesas Electronics is an RL78/G15 16-pin, 8 KB flash, 1 KB RAM, industrial-grade 8/10-bit MCU operating from 2.4 V to 5.5 V with −40°C to +125°C ambient rating. It integrates a 16 MHz high-speed on-chip oscillator (±1.0% accuracy at −20°C to +85°C), 7-channel A/D converter, 8-channel 16-bit timer array, and UART + dual simplified I²C + dual simplified SPI interfaces. It targets embedded motor control and industrial sensor nodes requiring robust timing, low-power operation, and integrated analog peripherals.
For engineers reviewing the R5F12048MSP#50 datasheet, R5F12048MSP#50 pinout, R5F12048MSP#50 application, or R5F12048MSP#50 equivalent, key selection criteria include its M-grade temperature support, SSOP-16 package with 0.65 mm pitch, 8 KB code flash with self-programming, 1 KB data flash rated for 1 million rewrites, and multiplexed analog/digital I/O supporting up to 7 ADC inputs and 2 comparators.
Technical Context
The R5F12048MSP#50 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution time of 0.0625 μs at 16 MHz. Its clock system supports flexible sourcing: high-speed on-chip oscillator (1–16 MHz), external crystal (1–12 MHz via X1/X2), or EXCLK input (1–16 MHz).
Power management includes HALT and STOP modes, selectable power-on-reset (SPOR) with four voltage thresholds, and dedicated low-speed on-chip oscillator (15 kHz) for watchdog operation. Peripheral integration includes TAU0 timer array (8 channels), SAU0 serial array unit (2 channels), and on-chip BCD correction logic for numeric display applications.

FAQ
What is the maximum operating frequency of the R5F12048MSP#50?
The R5F12048MSP#50 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, yielding a minimum instruction execution time of 0.0625 μs. External crystal (X1/X2) or EXCLK input can also run up to 12 MHz or 16 MHz respectively. The RL78 CPU core uses a 3-stage pipeline to maintain deterministic timing at all supported frequencies.
Does the R5F12048MSP#50 support in-system programming without external hardware?
Yes, the R5F12048MSP#50 includes an on-chip debug function that enables in-system programming via the TOOL0, TOOLRxD, and TOOLTxD pins. This eliminates the need for external debug probes during development, though Renesas cautions against using this feature in mass production due to flash endurance limits.
How many analog input channels does the R5F12048MSP#50 provide?
The R5F12048MSP#50 provides 7 analog input channels (ANI0 to ANI6) compatible with its 8/10-bit A/D converter. These channels are mapped to P00, P01, P02, P03, P04, P05, and P06 pins, supporting simultaneous sampling in applications like multi-sensor monitoring or motor phase current sensing.
What is the data flash endurance specification for the R5F12048MSP#50?
The R5F12048MSP#50 features 1 KB of data flash memory rated for 1,000,000 write/erase cycles (typical). Each rewrite operates on 32-bit units, and the full 1 KB block is organized into two 512-byte sectors-enabling wear-leveling strategies in firmware for long-term data logging or parameter storage.
Can the R5F12048MSP#50 operate reliably at +125°C ambient temperature?
Yes, the R5F12048MSP#50 is explicitly qualified for M-grade industrial operation from −40°C to +125°C ambient temperature. This qualification includes full functionality of its 8 KB flash, 1 KB RAM, 7-channel ADC, and all timers and serial interfaces under worst-case thermal conditions, making it suitable for sealed industrial enclosures and automotive under-hood applications.
